CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 430,247, dated June 17,1890.

Application filed April 14, 1890. Serial No. 347,880. (No model.)

To all whom it may concern:

Be it known that we, JOHN EDWARD DAVIS and CHARLES ALBERT LEWIS,citizens of the United States,residing at Olax,in the county of Custerand State of Nebraska, have invented certain new and useful Improvementsin Car- Couplings; and we do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the let ters'of reference marked thereon,which form a part of this specification.

This invention relates to certain new and useful improvements incar-couplings, and it has more particular reference to that class ofcouplings in which provision is made for antomatically coupling thecars, and in which provision is also had for readily uncoupling the samewithout the necessity of passing between the cars.

The invention has for its object to simplify and cheapen theconstruction and at the same time to render more serviceable inoperation this class of coupling devices.

To the above ends, and to such others as the invention may pertain, thesame consists in the peculiar construction and in the novel combination,arrangement, and adaptation of parts, all as more fully hereinafterdescribed, shown in the accompanying drawings, and then specificallydefined in the appended claim.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part .ofthis specification, like letters of reference indicating like partsthroughout the several views, and in which drawings- Figure l is aperspective view of a portion of acar provided with our improvedcoupling device. Fig. 2 is a central longitudinal vertical sectionthrough the drawhead and coupler.

Reference now being had to the details of the drawings by letter, Arepresents the draw-head, which is attached to the truck B of the car 0in the usual Way. The drawhead is made of cast metal, and the body ofthe draw-head is in the form of a single casting, provided with theusual horizontal slot A for the reception of the coupling-link, and thelower edge of the entrance to this slot is inclined downwardly, as shownat A so as to insure the ready coupling of cars in which the couplingattachments may diifer in height, as will be readily understood. Theupper face of the draw-head is provided with a central rectangularopening A having an extension or neck A, extending in the direction oftheopen end of the draw-head, as shown, while at the opposite or rearend of the opening the depression A in the upper face of the draw-headis provided for the reception of the operating-latch, as Will presentlyappear.

The coupling pin or hook D is made of cast metal and in substantiallythe form shown. The flat portion D of the hook or pin is adapted toenter the neck A and is pivotally retained therein by means of thetransverse rod or pivot D passed through a suitable opening formed forthe purpose in the draw-head. The body portion D of the hook D isadapted to fit Within the opening A with its lower end, when in place,resting within a depression or seat D formed Within the lower inner faceof the slot within the draw-head. It will be observed that when thehookD is in its normal or locked position thenpper face of the hook Willbe flush with the upper face of the draw-head, and that there will thusbe no uneven surfaces presented within which ice and snow mightaccumulate and possibly interfere with the free operation of the devicein the winter season.

E is a transverse rod, which is passed through a suitable opening formedfor its reception in the draw-head. This rod passes through the upperportion of the vertical opening A near its rear edge, and the ends ofthe rod are bent to form ,the operating cranks or handles E. The latch Fis secured at its rear edge to the bar E within the opening A andextends rearwardly, or in the direction of the rear end of thedraw-head, resting normally within the recess or depression A at therear end of the opening A and upon this latch normally rests theextension G of the hook D.

H is a vertical rod adapted to be moved vertically within suitableguides or keepers H, secured to the end of the car. This rod is designedto be of sufficient length to extend a short distance above the top ofthe car, and is provided at its upper end with a suitable handle 11,while at its lower end it is provided with a horizontal arm H which isconnected with the upper face of the hook D by a suitable link or chainH thus providing a convenient means for raising the said hook D from theroof of the car when it may be opening being provided at one of its endswith an extension, as A and at its opposite end with a depression A thecoupling-hook pivoted within the extension and adapted to normally closethe vertical opening with its upper face flush with the upper face ofthe draw-head, and the rod E, having operatingcranks at its ends andprovided at its longitudinal center with a latch, said latch beingfitted within the depression A beneath the end of the coupling-hook andadapted to raise the hook when actuated by the operating-lever,substantially as and for the purpose described.

In testimony whereof we affix our signatures in presence of twowitnesses.
